• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sach)) - thanh luan van ((cuong duong) OR (dong duong)) manh toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - thanh luan van ((cuong duong) or (dong duong)) manh toan cao".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sach)) - thanh luan van ((cuong duong) or (dong duong)) manh toan cao*.
